CM7 android system too high. - EVO 4G Q&A, Help & Troubleshooting

Okay so I noticed that even with the Tiamat kernal my battery life hasn't been great. I always see above 60% android system usage. I recently did the "GPS FIX" but I never upgraded my pri or NV. I need some help, I may skipped a step.

I would update all of your radios. Also, I think in settings under privacy, unclick back-up. Also, have you considered turning down how often your phone syncs?
It also could be a rogue app stealing resources... Let's start with my first suggestion, radios are in my Sig.

Okay this is weird, I turned off background data and now no system use. Is that saying it's a rogue app?

How many days was it high android use?
Sent from my PC36100 using XDA Premium App

Ever since I flashed the GPS fix but possibly after Google+ app. Either way its at 81% usage.
Sent from my PC36100 using XDA App

It's still high as hell ATM. 77% consumption. I don't understand. Wish I could get some help.

There is a fix for it you'll have to search for it I only saw it once
Sent from my PC36100 using XDA Premium App

Someone had a link for me in their sig but they changed it...and I searched to no avail. Sad cause I don't want to ditch cm7 for something so dumb. Just want my GPS to work without having my android system through the roof. Myn's Warm TwoPointTwo is on the other line. -.-

I had the same problem. Here's the fixes I did before I finally just ditched CM7
I updated my radios (and everything else).
All my syncs were on 4 hour intervals (except weather = 1 hour)
lowered screen brightness
uninstalled facebook, g+ and gVoice (my 3 highest used apps).
rebooted about 6 times
held it wrong
prayed to the gods of android
flashed Synergy RC2
So if you were considering doing those, don't. They aren't the problem.
Ironically, my GPS has never had a problem on any aosp rom (and I've tried darn near all of them), but like you, even with the kernels my stuff just wouldn't work right. I think it has something to do with our phones just not liking the kernel. Give toastch's "godmode" kernel a try or flash back to stock to see if that helps.

Ok so switch kernals or just switch to synergy?

Hydra kernels problems

Just tried every kernel Hydra has to offer and every one put my phone into a bootloop. Had to revert back to stock.
Any tips to get these working?

I just think some phones can take it, and some cant...thats all i can help
Sent from my ADR6300 using XDA App
I used the OC/UV ov, kernel #2 from Hydra. It was working ok but made my keyboard really laggy.
Sent from my rooted IncrediblÄ™
My keyboard is sometimes laggy but usually really fast. I've isolated the issue to the dictionary, I'm sure if auto suggest was off you wouldn't notice it.
Although, after using it for a day, the keyboard lag seems to have gone. Maybe it was repopulating or something.. no idea in this department.
Edit: these kernels are meant only for froyo

Random 100% cpu usage. A.k.a. AGGRAVATING LAG!

About 3 times a day, my evo will start to lag horribly. I check system pannel and it says the cpu usage is 100%. Then i look at the processes and theres like 3 apps running and then the normal system processes. Anyone know why?
Sent from my PC36100 using XDA App
Which apps are running and maxing your CPU usage? All 3 or 1 of 3 could be the culprit? Apps like Watchdog can tell you what app is blowing up and you can take it from there. I've had a few get out of hand and killing once or uninstalling / reinstalling has corrected it. Clearing data / cache for the app might help. Gotta figure out which ones are maxing it first.
blah blah effin blah
Usually its my normal stuff like handcent, lookout, ane maybe music. Its like one minute its fine and the next its lagging like crazy.
Sent from my PC36100 using XDA App
try what conqu1stador said with the watchdog app and if you still cant figure it out, try a different kernel.
Yeah i got the lite version. It looks like a very very nice app. Thanks for your replys.
Sent from my PC36100 using XDA App
So it just happened again, finally. I looked at Watchdog right away to see what was causing it, and turns out it wasnt an app at all. Its "Android System". Now, to be honest, im not really sure what that means ( im guessing it means my rom or OS or something like that). Can anyone shed some light on what is happening?
If it matters im running myns 2.2 rls5, and kings #9 kernel.

I was having a similar problem, figured out it was the stock voicemail app, froze it with TB and problem went away.

More than likely you're having the dreaded wakelock issue caused by the combination of baseband 2.15.00.11.19 & PRI 1.90_003. Downgrade your PRI to 1.77_003. That should alleviate the wakelock and battery drainage. If you do not have this combination, download and install the aLogcat app. After initiating the app, look for and pay attention to anything colored in red.
Only time this happens to me is when my phone is syncing my accounts

Radio draining battery

My radio has been draining my battery at a record pace recently. At 100% battery, I leave my phone on at night. Around 9 in ther morning, there is about 15% left. What could be the problem? I am running kings elite and have had great battery up until about a week ago.

What leads you to believe its your radio that is causing it? It could be a run a way app, locking your CPU at 100%. Have you checked your up time vs awake time to see if you have a wake lock? If you do, the times will be the same, or very.close to the same. What radio and pri are you currently using? Sometimes the 1.90 pri will cause massive battery drain. Changing to pri 1.77 usually solves that issue.
Sent from my PC36100 using XDA App
I've turned my radio off at night and the battery only drops maybe 10% at most.
Edit
But I will try down grading my radio.

That doesn't necessarily mean its your radio for sure. It could be that an app is using the radio, sending and receiving data. Also, using spare parts is good for tracking down a runaway app

You're welcome. Also, sometimes if I've I'm not too attatched to the setup I'm using, and I happen to have some battery issues...I'll just do a complete wipe, and re flash the rom. Start fresh, and download all my apps again from the market, and install them one at a time. Then I monitor after each app I install, before installing another. Kind of tedious, but sometimes if you can't figure out what's causing a massive battery drain, that's the best way. You know you have a clean start.

Even if you were attached, you can still backup your launcher settings, and apps in titanium, then you can figure it out, and then go back.

You speak the truth! I just like doing things the long way, haha. I find it refreshing to start clean and fresh, without restoring anything I have saved. Just a total clean start. I guess I'm crazy, lol.
Well I think I may have found the culprit. Seems I was signed into latitude. Until I signed out my up time and awake time were identical. Now things are looking like they are getting back to normal.

There is a thread by Calkulin, that has all radios, hboot, pri, wimax versions. Its in the dev section. Download the 1.77pri, and flash in recovery. All of the ones linked in calkulins thread are flashable in recovery. I would link you to it, or attach a copy for you, but I'm on xda app. And no, you don't need to be on a sense rom to flash the pri. Maybe you were thinking of the prl, which you do need to be in a sense rom to update.

[Q] Best kernel to use with the Kinged SHOOTER E3D Rom?

What kind of battery life are you getting?
I am using GM that is baked with the ROM and it works great. I tried Freedom and I received a lot of FC. I set SetCPU to 998/245 and I am getting around 15 hrs with moderate use.
So if i use the stock kernel and setcpu app with this rom, will this make any difference on performance &/or battery life?
Sent from my PC36100 using XDA Premium App
I'm getting 14-15 hours with light use.You can use setcpu with the stock kernel to enforce lower clock speeds with the screen off.The newer kernels may have it built in but I prefer to use setcpu so I know exactly what's happening.
Sent from my PC36100 using XDA App
TY! I got 15 hrs on stock and no setcpu, but something i did notice about this rom is the display goes to the top brightest setting on its own and the icons disappear from the home screen after a reboot.... but awesome rom so far!
Sent from my PC36100 using XDA Premium App
Havnt run into the brightness issue,for the apps disappearing,after a reboot,choose a scene other than the one you normally run and then change it back to the one you normally use and the icons will be back to normal.

"Lazy" 4g responsiveness

Hey all.
I have had an issue for a long time on deodexed fc09 roms. I thought it was an issue with the specific rom I was using but think it is an issue with the rom that rom was built on. I am using the stock (for the first time) fc09 posted that is deodexed and has su and I think some kernel tweaks built in and I notice the same issue. My 4g sleeps and does not promptly wake upon an attempt at data transmission. Frequently I wait 5 seconds and often even need to refresh the page or action. Anyone have a clue as to why or whay I can change to improve it?

Mine does that. I hardly ever use 4g unless I'm downloading a large file. So it was never a big deal for me. I don't remember if it did it on eclair or froyo roms. Its been so long...
